BACKGROUND: The purpose of this clinical study was to assess the effects of different rapid maxillary expansion appliances on the severity of obstructive sleep apnea (OSA).
MATERIAL AND METHODS: Patients having a narrow maxilla and identified with OSA were divided randomly into three groups: tooth tissue-borne, tooth-borne, and bone-borne expanders. Changes in sleep parameters at baseline and 3-month follow-up detected by polygraphy were the primary outcome. Treatment of the crossbite was the secondary outcome. Dunn-Bonferroni tests, Kruskal-Wallis, and Wilcoxon analysis were applied for intra- and inter-group differences at p < 0.05 significance level.
RESULTS: Among 46 patients randomized, apnea-hypopnea index (AHI) changed from baseline to follow-up in all groups (- 1.6, p = 0.280; 0.6, p = 0.691; - 0.45, p = 0.796, respectively), with no between-group difference (p = 0.631). Oxygen desaturation index (ODI) altered from baseline to follow-up in all groups (0.80, p = 0.977; 0.20, p = 0.932; and - 1.00, p = 0.379, respectively), with no between-group difference (p = 0.858). There was no significant difference in minimum oxygen saturation from baseline to follow-up in all groups (0.00, p = 0.401; - 2.00, p = 0.887; 0.50, p = 0.407, respectively). No significant changes were observed in supine AHI from baseline to follow-up in all groups (0.00, p = 0.581; - 1.00, p = 0.393; 0.00, p = 0.972, respectively). The upper intermolar width increased from baseline to follow-up in all groups (5.04, p = 0.000; 3.15, p = 0.001; 5.41, p = 0.00, respectively) with no between-group difference (p = 0.560). Maxillary width increased from baseline to follow-up in all groups (4.25, p = 0.001; 4.74, p = 0.00; 4.49, p = 0.001, respectively) with no inter-group difference (p = 0.963).
CONCLUSIONS: The amount of skeletal and dental expansion obtained in the maxilla was similar in all groups. Rapid maxillary expansion was not found to be effective in OSA treatment.
